For more than a dozen years Professional Security magazine has each month provided pages of news, views and case studies on products and services using Internet Protocol (IP).
Not only can CCTV for instance be integrated with other electronic security devices, such as intruder alarms, and access control, but other non-security equipment such as BMS (building management systems) can run over IP.
The US-based body ONVIF (Open Network Video Interface Forum) seeks the adoption of IP in the security market. The ONVIF specification aims to ensure interoperability between products regardless of manufacturer. For details visit http://www.onvif.org. According to ONVIF, whose members include such multi-nationals as Axis, Bosch, Honeywell, Pelco by Schneider Electric, Siemens and Sony, the goal is to make it even easier for end users, integrators, consultants and manufacturers to take advantage of the possibilities offered by network video solutions. An open standard for the interface of network video products enables them to integrate products from vendors into a single solution.
A related issue is the security of the network. For example a Denial-of-Service (DoS) attack as defined by the official CPNI involves a malicious attempt to disrupt the operation of a computer system or network that is connected to the Internet. The most common form of attack is one which disrupts the operation of the computer system or network by consuming the bandwidth of the victim network. And as industrial control systems have been connected to a network, they – whether power stations or the warning signs for drivers on motorways – can be vulnerable to hacking. As CPNI says, almost all critical industrial infrastructures and processes are managed remotely from central control rooms, using computers and communications networks. The flow of gas and oil through pipes, the processing and distribution of water, the management of the electricity grid, the operation of chemical plants, and the signalling network for railways.
